An 83-year-old man, 9 years after repair of a postinfarction aneurysm of the left ventricle, developed fever, anemia, and congestive heart failure. Extensive evaluation of the gastrointestinal tract revealed no evidence of ulcer disease. While in the hospital, he developed massive hematemesis and melena and died 2 days later. At autopsy, a communication existed between a left ventricular pseudoaneurysm and the stomach to form a cardiogastric fistula. Infection of the left ventricular pseudoaneurysm may have precipitated the gastric perforation. This represents an extremely rare late complication of aneurysmectomy procedures and, to our knowledge, is the first case to be reported in the absence of primary gastrointestinal pathology.

Body condition, hepatosomatic index and blood chemistry of Oncorhynchus mykiss experimentally infected with a tissue dwelling fish pathogenic fungus, Ichthyophonus hoferi, were monitored over a 6 wk period. This was to determine whether the infection constituted a stress manifest by changes in the hypothalamic-pituitary interrenal axis, and especially plasma cortisol levels. Infection caused anaemia and leucopenia but did not change the condition, hepatosomatic indices, or plasma chloride, cholesterol, cortisol, creatinine, glucose, osmolarity, potassium, total protein, sodium and T4. It is suggested that increased cortisol levels may not be a normal component of the stress response of fish to disease caused by invasive infectious agents.

Infection of cattle with various stocks of Trypanosoma brucei rhodesiense indicated that 49% developed a fatal CNS disease comparable to that found in man. Duration of disease ranged from 85 to 1613 days post infection. All eight stocks of T. b. rhodesiense tested, including those from Ethiopia and Tanzania, induced CNS disease. Blood became positive three to five days after inoculation, and after an initial peak of parasitaemia remained positive for three to five months. Subinoculation of blood into rodents subsequently became negative, although trypanosomes persisted in the lymph nodes for at least 56 to 1613 days. Only animals with CNS disease had detectable parasites in the CSF, usually after the animals had undergone severe deterioration. At post mortem examination trypanosomes could usually be found in the lymph nodes and CSF, and occasionally in the blood. Clinical signs included fever, hyperkinesia, weight loss, cerebellar ataxia, tremor, salivation and hyperaesthesia. A mild to moderate anaemia accompanied a transient thrombocytopenia and leucopenia. Animals subsequently developed leucocytosis. A pleocytosis and elevated total protein in the CSF was found, which persisted in some animals for long periods. Histopathological examination of the brain showed prominent generalized perivascular infiltrates consisting mainly of lymphocytes and plasma cells. Mott's cells were regularly observed. Vascular changes were characterized by swollen endothelium, infiltration of the vascular wall by inflammatory cells, and in some instances perivascular oedema. In the most severe cases evidence of ischaemia consisted of large numbers of astrocytes, rarefaction of the parenchyma, and areas of necrosis with loss of normal architecture. Demyelination was limited to perivascular areas. Occasionally a moderate to severe pancarditis was found.

We have analysed 139 consecutive cases (71 males and 68 females) of nutritional megaloblastic anaemia over a period of four and a half years. The majority of these patients belonged to the low socio-economic class and many of them were strict vegetarians. Sixty one percent were in the second and third decades of life. At the time of presentation, 46% had mild hepatomegaly, 42% fever, 34% mild splenomegaly and 20% bleeding manifestations. Of 102 cases in whom the biochemical parameters were available, vitamin B12 deficiency was detected in 76%, folate deficiency in 6.8%, combined B12 and folate deficiency in 8.8%; the remaining 7.8% had normal vitamin levels at presentation. All 139 patients had severe anaemia, 80.5% had thrombocytopenia and 43.8% had neutropenia as well as thrombocytopenia. It appears that during progression (in terms of duration) of megaloblastosis, anaemia is followed by thrombocytopenia and then neutropenia. Infection and bleeding in these patients may be aggravated by impaired functions of neutrophils and platelets, respectively.

Ten patients with plasma cell leukaemia (PCL), out of 259 cases of multiple myeloma diagnosed in the Haematology Service of the University Hospital of Barcelona in the last 18 years, are presented. Of the 10 PCL cases, 5 were primary and 5 were secondary. Anaemia and thrombocytopenia, along with massive plasma cell infiltration of the bone marrow, were the most striking findings. Osteolytic lesions were present in 9 of the cases and liver involvement in two. Chemotherapy including vincristine and prednisone was administered to eight patients, associated to alkylating agents (melphalan and/or cyclophosphamide) in six of them. Four of these patients received also adriamycin and BCNU. Two objective responses were achieved, lasting for 10 and 3 months, the remaining six patients failed to respond. The median survival for all the PCL patients was less than one month (ranging between 0.2 and 14 months). None of the secondary PCL patients survived for 2 months after diagnosis. Infection (3 cases of septicaemia and 3 of pneumonia), renal failure (2 cases) and liver insufficiency (1 case) were the causes of death in the nine deceased patients. The therapeutic possibilities for this severe haemopathy are discussed.

Infection with Eperythrozoon suis (E. suis) normally takes a latent course and depends on various factors. Only animals suffering extreme stress show clinically manifest attacks with anemia, fever and occasionally jaundice. Stress in the form of high animal-concentration in the stables, poor climatic conditions, change of stables or food or chronic general diseases predispose the pigs to clinical illness. The diagnosis of E. suis infection is made difficult by the prevalence of general diseases in the stocks. Experimental infections have shown that also latent infections with E. suis cause partly significant deviations in the red and white blood cell count as well as in the glucose and acid-base balance and lead to serologically detectable immune reactions which could be used as a basis for stock-diagnosis. It is still unknown to what extent infection with E. suis represents a factor in the manifestation of other complex diseases. Some observations, however, give reason to believe that Eperythrozoonosis as a basis infection is itself a precursor for the manifestation of widespread infectious diseases.

Infection of BALB/c mice with the RLV-A virus typically results in an erythropoietic dysplasia characterized by hepatosplenomegaly, erythroblastosis, erythroblastemia and severe anemia without reticulocytosis. Mice hypertransfused weekly with 75%-packed red cells for 42 days prior to RLV-A infection and viral potency controls manifested this typical RLV-A response. Mice that were hypertransfused prior to and following RLV-A infection never developed the "typical" RLV-A pathogenesis. Instead, a transplantable myeloid leukemia was established. Although the reason for altered pathogenesis remains uncertain, it seems plausible that continued hypertransfusion, presumably after establishment of an altered granulopoietic microenvironment, resulted in a completely different viral expression and development of the transplantable myeloid leukemia.

Twenty calves were orally inoculated with Mycobacterium paratuberculosis at six weeks old. At six months old, 10 of these, plus four uninfected controls were maintained on limited dietary copper and supplemented iron intake for a further 27 months. During this time all these animals, together with a further four untreated controls, were bred before being killed and examined for evidence of paratuberculosis. Despite significant reduction in weight gain, attributable to both iron supplementation and infection, no significant difference was found in the numbers of iron-supplemented and unsupplemented animals that developed clinical signs nor in the extent and severity of intestinal lesions between groups. Accumulation of iron in paratuberculosis lesions was not affected by iron supplementation but was positively correlated with the frequency of shedding of M paratuberculosis in faeces (P less than 0.05). Dietary iron supplementation alone resulted in serum hyperferraemia, hepatic siderosis and slight hypocuprosis, whereas, in infected animals, this resulted in marked hypocuprosis and anaemia within groups (P less than 0.05). Infection alone resulted in serum hypoferraemia and intestinal and hepatic siderosis which was positively correlated with the severity of infection within groups (P less than 0.05). Susceptibility to paratuberculosis may result from failure ultimately to limit monokine-mediated iron sequestration in intestinal tissue.

Infection of Ayrshire cattle with a stock of Trypanosoma vivax from the Galana Ranch, Kenya, resulted in an acute disease characterised by profound anaemia and haemorrhage, which reached maximum severity between 3 and 5 weeks after infection. Bleeding from the ears, nose and rectum occurred. At necropsy, petechial and ecchymotic haemorrhages were widespread, but were particularly severe in the gastrointestinal tract. In confirmation of the gross findings, congestion, haemorrhage and degenerative changes in most tissues and organs were found histologically. Thrombi were seen in the lymphatic vessels and clots of fibrin were present in the ventricles of the brain. The anaemia was a consequence of frank blood loss through haemorrhaging, exacerbated by erythrophagocytosis of deformed red blood cells, whose occurrence was indicative of microangiopathic changes. Animals were euthanised between 23 and 36 days after infection when they became recumbent with PCV values as low as 9%. There is no doubt that animals affected by this syndrome in the field would die within a few weeks of infection, if left untreated.

Infection with Capillaria philippinensis has not been reported in Taiwan before. It is characterized by chronic diarrhea, abdominal pain and muscle wasting. Because the infection results in a severe disease with a high mortality, early diagnosis is very important. A 58-year-old housewife from Ar-Lien village, Kao-Hsiung County, was admitted to the National Taiwan University Hospital in July 1988, after suffering from diarrhea, lower leg edema and weight loss for one year. The initial symptom was epigastric pain followed by watery diarrhea. Thereafter borborygmus, frequent loose stool passage and weakness persisted. The cause of her malabsorption syndrome went undetected until the ova, larvae and adult worms of C. philippinensis were detected in the direct smear of the patient's stool in August 1988. She received mebendazole 200mg b.i.d. for 20 days. Capillaria ova were no longer detected following the third day of medication. At the second month follow-up, her body weight returned to her pre-morbid state and all laboratory findings returned to normal with the exception of mild anemia. The infection source was not clear.
